A Theory of Everything Remains Beyond Today’s Experimental Reach

Fermilab particle physicist Don Lincoln uses a Lex Fridman interview to argue that modern physics is still organized around unification, but that the next step is unlikely to come from elegant theory alone. Lincoln says the Standard Model remains highly successful within its domain, while dark matter, dark energy, the matter-antimatter imbalance and quantum gravity mark places where the framework is incomplete. His case is that progress toward a grand theory will depend less on belief in candidate theories such as string theory than on measurements sharp enough to force nature’s hand.
